The fiber optic patch cord (also called a fiber jumper) is used to connect an optical splitter to other network devices.

A fiber optic patch cord is a short, flexible optical fiber cable with connectors on both ends, designed to interconnect optical devices such as splitters, patch panels, switches, and transceivers . It acts as a “bridge” that transmits light signals accurately over short distances, typically from a few meters up to several tens of meters . These cords are essential in FTTH networks, data centers, and telecom systems for flexible and plug-and-play connections .

Key Features

• Connectors: Common types include LC, SC, ST, FC, MPO, and MTP, chosen based on equipment compatibility and network density .
• Fiber Type: Single-mode (OS1/OS2) for long-distance or backbone links, and multimode (OM1/OM2/OM3/OM4/OM5) for short-distance, high-speed connections .
• Simplex vs Duplex: Simplex cords have one fiber for one-way transmission, while duplex cords have two fibers for bidirectional communication, often used in Ethernet and PON links .
• Jacket Material: Options like PVC, LSZH, OFNR, or OFNP provide environmental protection and compliance with fire codes .

Applications with Optical Splitters

• FTTH Networks: Connects the optical line terminal (OLT) to the splitter and then to optical network terminals (ONTs).
• Data Centers: Links splitters in distribution frames to switches or servers.
• Telecom Networks: Facilitates flexible routing and reconfiguration of optical signals between splitters and other devices. In summary, the fiber optic patch cord or fiber jumper is the standard cable used to connect an optical splitter to other optical devices, providing low-loss, flexible, and reliable connections in modern optical networks .
